Netgate 6100 ZFS reinstall disk space
-
Hi, I have added a custom 512 GB SSD to my Netgate 6100 and reinstalled pfSense ZFS over it. Everything is working fine and I know there is nothing wrong here but I am just trying to understand how the space is reported by each of the tools. diskinfo reports 477GB in bytes and the pfSense zpool list is 472GB. Where are the missing 5 GB? If I look gpart then freebsd-zfs is 475GB and freebsd-swap is 2 GB which adds up to 477GB on nvd0 but that's different than zpool list (472GB). Thanks!

That's the available space in the pool so I would have to say the capacity that appears to be 'lost' is in the filesystem formatting. I've never really looked into that too deeply though.
